segmentSet

Generate and filter infinite-style segment fields (PGS hatching building blocks).

Imports

import {
  parallelSegments, weaveSegments, stochasticSegments,
  perpendicularPathSegments,
  filterByMinLength, filterAxisAligned,
  segmentLength, segmentsToOpenPaths, clipSegmentsToPath,
  segmentSet,
} from 'pattapatta'

Functions

Function	Description
`parallelSegments(…)`	Parallel line field (float32-compatible spacing)
`weaveSegments(w, h, cellSize, A, B, C, opts?)`	ABC fabric H/V runs in a box
`stochasticSegments(w, h, n, minLen?, maxLen?, seed?, ox?, oy?)`	Random non-intersecting segments
`perpendicularPathSegments(path, spacing, length, startOffset?)`	Perimeter-normal ticks
`filterByMinLength(segs, min)`	Drop short segments
`filterAxisAligned(segs)`	Drop near-axis-aligned segments
`segmentLength(seg)`	Length
`segmentsToOpenPaths(segs)`	Convert to open `Path`s for `toSvg`
`clipSegmentToPath` / `clipSegmentsToPath`	Clip lines to a polygon

Example

Raw parallelSegments field (muted) clipped to a circle (accent):

Parallel segments clipped to a circle

const cell = createCircle(50, 50, 32, 64)
const raw = parallelSegments(50, 50, 55, 7, Math.PI / 5, 18)
const clipped = clipSegmentsToPath(raw, cell)

Prefer the hatch helpers for filled regions.
